1. Safety precautions

1.1 Basic safety instructionsIn addition to the safety precautions listed in the indi-vidual sections of these operating instructions, thefollowing points must be strictly observed at all times.

1.2 Only use Hilti cartridges or cartridges of equiva-lent quality

The use of cartridges of inferior quality in Hilti tools maylead to build-up of unburned powder, which may explo-de and cause severe injuries to operators and bystan-ders. At a minimum, cartridges must either:

a) Be confirmed by their supplier to have been suc-cessfully tested in accordance with EU standard EN16264

NOTE: All Hilti cartridges for powder-actuated tools have

been tested successfully in accordance with EN 16264. The tests defined in the EN 16264 standard are system

tests carried out by the certification authority usingspecific combinations of cartridges and tools.The tool designation, the name of the certification aut-hority and the system test number are printed on thecartridge packaging.

or

b) Carry the CE conformity mark (mandatory in the EUas of July 2013).

See packaging sample at:www.hilti.com/dx-cartridges

1.3 Use as intendedThe tool is designed for professional use in fasteningapplications in construction where nails, threaded studsand composite fasteners are driven into concrete, steeland sand-lime block masonry.

1.4 Improper use Manipulation or modification of the tool is not per-missible.Do not operate the tool in an explosive or flammableatmosphere, unless the tool is specially approved forsuch use. To avoid the risk of injury, use only original Hilti fas-teners, cartridges, accessories and spare parts or thoseof equivalent quality.

Never point the tool at yourself or any bystander.Never press the muzzle of the tool against your handor other part of your body.Do not drive nails into excessively hard or brittle mate-rials such as glass, marble, plastic, bronze, brass, cop-per, natural rock, insulation material, hollow brick, glazedtile, thin-gauge sheet metal (< 4 mm), grey cast iron,

spheroidal cast iron and gas concrete.

1.5 Technology This tool is designed with the latest available tech-nology. The tool and its ancillary equipment may present haz-ards when used incorrectly by untrained personnel ornot as directed.

1.6 Making the workplace safe Ensure that the workplace is well lit.Objects which could cause injury should be removedfrom the working area.Operate the tool only in well-ventilated working areas. The tool is for hand-held use only.Avoid unfavorable body positions. Work from a securestance and stay in balance at all timesKeep other persons, children in particular, outside theworking area. Before using the tool, make sure that no oneis standing behind or below the point where fasteners

are to be driven. Keep the grip dry, clean and free from oil and grease.

1.7 General safety precautions Operate the tool only as directed and only when it isin faultless condition.Use the stabiliser/splinter guard when the applicationpermits. If a cartridge misfires or fails to ignite, proceed as fol-

lows:1. Keep the tool pressed against the working surface for

30 seconds.2. If the cartridge still fails to fire, withdraw the tool from

the working surface, taking care that it is not pointedtowards your body or bystanders.

3. Manually advance the cartridge strip one cartridge.Use up the remaining cartridges on the strip. Removethe used cartridge strip and dispose of it in such away that it can be neither reused nor misused.

If 23 cartridge firing with reduced driving poweroccur in succession (without clearly audible noise of thecartridge firing and the fastener being driven with sig-nificantly less power), proceed as follows:1. Stop using the tool immediately.2. Unload and disassemble the tool (see 8.3).

3. Check that the correct combination of fastener guide,piston and fastener are used (see 6.2).

4. Check the buffer, piston and fastener guide / maga-zine for wear and replace the parts if necessary (See6.3 and 8.4. X-IE see 8.5).

5. Clean the tool.6. Do not continue to use the tool if the problem per-

sists after carrying out the steps described above.Have the tool checked and repaired if necessary at aHilti repair center.

Never attempt to pry a cartridge from the magazinestrip or the tool. Keep the arms flexed when the tool is fired (do notstraighten the arms). Never leave the loaded tool unattended. Always unload the tool before beginning cleaning,servicing or changing parts and before storage.Unused cartridges and tools not presently in use mustbe stored in a place where they are not exposed to humi-

dity or excessive heat. The tool should be transportedand stored in a toolbox that can be locked or secured toprevent use by unauthorized persons.

1.8 Temperature Do not disassemble the tool while it is hot. Never exceed the recommended maximum fastenerdriving rate (number of fastenings per hour). The toolmay otherwise overheat.

Should the plastic cartridge strip begin to melt, stopusing the tool immediately and allow it to cool down.

1.9 Requirements to be met by users The tool is intended for professional use. The tool may be operated, serviced and repaired onlyby authorised, trained personnel. This personnel mustbe informed of any special hazards that may be encoun-tered. Proceed carefully and do not use the tool if your fullattention is not on the job. Stop working with the tool if you feel any pain or dis-

comfort.

1.10 Personal protective equipment

The operator and other persons in the immediate vicin-ity must always wear approved eye protection, a hardhat and suitable ear protection.

3. Description

The tool is designed for professional use in fasteningapplications where nails, threaded studs and compositefasteners are driven into concrete, steel and sand-limeblock masonry.

The tool works on the well-proven piston principle andis therefore not related to high-velocity tools. The pis-ton principle provides an optimum of working and fas-tening safety. The tool works with cartridges of 6.8/11caliber.

The piston is returned to the starting position and thecartridges are fed to the firing chamber automaticallyby gas pressure from the fired cartridge. This permitsfastenings to be made very quickly and economicallywith nails and threaded studs. The use of a nail maga-zine greatly increases the speed and convenience of fas-tening with the tool, above all when making large num-bers of identical fastenings of all kinds.

As with all powder-actuated tools, the tool, magazine,fastener program and cartridge program form a tech-nical unit. This means that optimal fastening with thissystem can only be assured if the fasteners and car-tridges are specially manufactured for it, or products ofequivalent quality, are used. The fastening and applica-tion recommendations given by Hilti are only applicableif these conditions are observed.

The tool features 5-way safety for the safety of the

operator and bystanders.

The piston principle

The energy from the propellant charge is transferred toa piston, the accelerated mass of which drives the fastener

into the base material. As approximately 95 % of thekinetic energy is absorbed by the piston, the fastener isdriven into the base material at much reduced velocity(less than 100 m/sec.) in a controlled manner. The dri-ving process ends when the piston reaches the end ofits travel. This makes dangerous through-shots virtual-ly impossible when the tool is used correctly.

The drop-firing safety device is the result of cou-pling the firing mechanism with the cocking move-ment. This is designed to prevent the Hilti DX tool fromfiring when it is dropped onto a hard surface, no mat-

ter at which angle the impact occurs.The trigger safety device ensures that the cartridgecannot be fired simply by pulling the trigger only. Thetool can be fired only when pressed against the surface.

CAUTION

The tool can get hot while oper-ating.

You could burn your hands. Do not disassemble the tool while

it is hot. Let the tool cool down.

8. Care and maintenance

When this type of tool is used under normal operatingconditions, dirt and residues build up inside the tooland functionally relevant parts are also subject to wear.Regular inspections and maintenance are thus essen-tial in order to ensure reliable operation. We recom-

mend that the tool is cleaned and the piston and pistonbrake are checked at least weekly when the tool is sub-jected to intensive use, and at the latest after driving10,000 fasteners.

8.1 Care of the toolThe outer casing of the tool is manufactured from impact-resistant plastic. The grip comprises a synthetic rubbersection.The ventilation slots must be unobstructed and keptclean at all times. Do not permit foreign objects to enterthe interior of the tool. Use a slightly damp cloth to clean

the outside of the tool at regular intervals. Do not use aspray or steam-cleaning system for cleaning.

8.2 MaintenanceCheck all external parts of the tool for damage at regu-lar intervals and check that all controls operate proper-ly. Do not operate the tool when parts are damaged orwhen the controls do not operate properly. If necessary,have the tool repaired at a Hilti service centre.

Servicing the toolThe tool should be serviced if:1. Cartridges misfire2. Fastener driving power is inconsistent

3. If you notice that: contact pressure increases, trigger force increases, power regulation is difficult to adjust (stiff), the cartridge strip is difficult to remove.

CAUTION while cleaning the tool:Never use grease for maintenance/lubrication of toolparts. This may strongly affect the functionality of thetool. Use only Hilti spray or such of equivalent quality. Dirt from DX tool contains substances that could beendangering your health.

Do not breath in the dust from cleaning Keep dust away from food Wash your hands after cleaning the tool

8.3 Disassemble the tool1. Ensure that no cartridge strip or fastener is loaded in

the tool. Remove the cartridge strip by pulling itupwards out of the tool and remove the fastener fromthe fastener guide.

2. Press the release button located at the side of the fas-tener guide.

3. Unscrew the fastener guide / magazine.4. Remove the buffer by bending it away from the fas-

tener guide / magazine.5. Remove the piston.

8.4 Check the buffer and piston for wear

Replace the buffer if: the metal ring is loose or broken, the buffer no longer holds on the fastener guide, excessive, uneven wear beneath the metal ring isnoticed.

Replace the piston if: it is broken,
